LIGHTING ATTACHMENT FOR GAS-BURNERS.

SPECIFICATION forming part of Letters Patent No. 738,711, dated September 8, 1903. Application filed March 3.1903. Serial No- 145, 78; on model.)

To all whom it may concern:

Be it known that I, ARTHUR GLANVILLE GHUBB, manager of company, a subject of the Kingof Great Britain, residing at The Lilacs,

Ironbridge, in the county of Salop, England, have invented certain new anduseful Improvements in Lighting Attachments for Gas Burners,.of which the following is a specification.

1 This invention has relation to lighting or igniting attachments principally adapted for use in connection with the burners of street gas-lamps, but also applicable to other gasburners for general illuminating and heating purposes; and the object ofthe said invention as applied to street-lamps and other lamps and gas-fittings is to provide. a simple and eitective attachment whereby the burner of the lamp responding parts in the several figures of the drawings. a

; a In carrying out this form of theinlvention may be easily lighted and without it being necessary to open' the lamp or fit the same with flaps to admit of the introduction of a light ora lighting-torch into the interior thereof.

According to the said invention it is proposed to effect the lighting of the burner of a street gas-lamp or other lamp by providing the said lamp with means whereby an explosive mixture of gas and air is formed within a tube or pipe leading from the outside of the lamp to theburner simultaneous with the ad mission of a limited supply of gas to the burner itselt and by providing for the ignition of this mixture by an external jet,which is lighted from an ordin ary torch or other lighter,

H the flame resulting from the explosion being conducted to the burner for lighting the gas supplied thereto, after which the full supplyof gas is turned onto the burner, this motion being utilized to automaticallycut oi the supply of gas to the lighting attachment.

t Figure 1 of the accompanying drawings represents a vertical section (but with parts in elevation) of an incandescent gas-burner for street-lamps or the like constructed and provided withsupplementary lighting devices or attachments in accordance with this invention. This view shows the levers or turns of the cocks which respectively control the main gas-supply to the burner and the initial supply to the lighting attachment in the positions in which they are placed when. the said initial supplyis full on and the main supply is cutoff. Fig. 2 shows a horizontal section of Fig. 1 upon the dotted line 00. Fig. 3 shows a complete vertical section of the'fittings upon the dotted line ,Fig. 2,which is taken through both the cooks and throughthe external nipple, the cock of the lighting-up attachments being represented in its open position, while the main supply-cock is closed. Fig. 4: is a similar sectional view to that represented in Fig. 3 5 but the lighting-up cock is closed and themain cockis opened to admitof theiull gassupply passing to the burner. Fig. 5 also shows a similar section to that represented in Figs. 3 and l; but in this view the two cocks are closed and gas is out 01f from both the main burner and the auxiliary lighting-up devices.

The same letters of reference indicate corin its application to a str'eetlamp, as shown in Fig. 1, the pipe a, which conveys the gas to the burner a, is arranged to support an auxiliary lighting-tube or ignition-pipe b, the open upper end I) of which is located adjacent through the bottom 0 of the lamp-body cto 'the outside thereof and terminates in a hood ordomed, coned, orother expandedor enlarged {mouth b ,the ignition-tube are supported above the Both the main burner-tube and casing or, body part cl of a double-cock fitting (1, provided with two cocks e and f and two 'gasways or passages e f, the former of which *to the burner, while the lower end extends supply to the burner and ignition devices and leads fromthe said service-pipeintoabranched chamber g, the one branch, g, of which communicates with the part of the gasway e wherein the plug of theburner-cock works, and the other branch, g is directed to a nipple or nozzle h, located below and in a line with the bore of the ignition-tube b. i

In thearrangement shown in the drawings in addition to part of the initial supply of gas (through the opening of the plug f) passing into theburner-tubed by way of the branch g and another part passing through the-nippleh into the ignition-tube I), where it forms an explosive mixture with the drawn-in air, a third portion of the said initial supply is led into a supplementary jet-pipe'n, which leads from the chamber g of the cock-casing upwardly along one side of the ignition-tube b, and its upper termination 41' is directed or located over the open upper end I) of the said tube, so that the gas issuing therefrom is ignited inthe manner hereinafter explained by the flame resulting from the explosion of the mixture in the ignition-tube and forms a pilot-light which remains alight so long as gas is passing through the plug f and serves to ignite that part of the initial supply which is directed to the burner, thus rendering the lighting attachment more positive or certain in its action, although it is to be understood that in someicases the burner may be lighted directly by the flash of flame resulting from the explosion of the mixture in the ignition-tube without the intervention of the said pilotlight. a

The nipple h for conveying the gas to the ignition-tube to form the explosive mixture therein is inclosed Within a wind-screen box orchamber 0, located Within the hood at the bottom of the ignition tube 1) and communicating at its upper end directly with the said tube, this chamber being provided with a series of air-holes 0, formed around the lower part of the outer walls for the admission ofthe air which is to be mixed in the upper part of the said chamber with the gasissuing from the hole 71/ in the summit of the nipple. This nipple is pierced down one side with a series of smalljet-holes 71 and the opposite'part of the walls of the chamber 0 is formed with a nozzle or openingzo wherethrough the streams of gas issuing from the said jet holes 7& are projected when the initial gas-supply is admitted to the lighting attachments, so that when a been formed inthe ignition-tube, and as the respective streams of gas are protected by the casing from the disturbing influences of high winds and the like their respective functions are not interfered with, and the appliance is rendered positive in its action under all conditions. g

The plug of the burner-cock is provided on its periphery with a groove e extending from the lower end of the plugasway e to such a distance that when the said burner-plug is in its closed or cut-01f position and the lightingup plug is open, as represented in the sectional View Fig. 3, gas may pass from the chamber 9 by way of the said groove 6 to the burner-tube a, so that when the cooks are in this position the gas entering the chamber 9 is divided, one part being supplied to the burner ,While the otherportion is further subdivided, part of the same passing to the nipple h, through the perforation in its tip, and thence into and up the ignition-tube, where it forms an explosive mixture of gas and air which is utilized for lighting the initial gassupply at the burner, while the other part passes up the pilot-light tube n. ()n the other hand, when the initial-supply plug f is closed and the burner-plug is fully opened, as shown in the sectional view Fig. 4:, communication between the burner-tube and the chamber g is closed by a solid or ungrooved part of the said plug being brought over the end of the branch 9, and thus the whole of the gas-from the service-pipe passes directly to the burner.

The operation of a lighting attachment constructed in accordance with the foregoing de= scriptionis as follows: When the initial supply is turned on by the opening of the cock f, and a torch or the like is applied to the mouth of the nozzle 0 the stream of gas issuing therefrom is first ignited, andthen under the influence of the upward draft created by the rising aincurrehts Within the i nition-tube this name is made to strike inward,

or light back into the interior of the chamber- 7 0-, whereby the mixture of gas and air within the i gni tion-tube is exploded and the flame created by the explosion is carried up the saidtube into the interior of the lam p, where it lights the gas issuing from the supplementary pipe-n, thereby establishing a pilot-light, from which the initial supply of gas to the b'urnerbecomes ignited, The full supply of gas is now turned .onto the burner by opening the cock 6, which at the same time closes the communication between the burner-tube and the initia1=su pry cock, and in order to automatically and simultaneously out oh": the initial supply to the bnrner, the nipple h, and the pilot-light vthe plug of the said cock 6 is provided with a double-armed leverj, whose movement in both directions is limited by stopsjj on its lower edges, adapted to come against a peg f, standing from the side of the plug-easing; The one armor branchj of the said lever has a stud or right-angled projection f arranged to overhang or come in the path of an arm or extension 7c of the lever 7c of the initial-supply cock f,'the arrangement of the several parts being such that when the burner cock lever j is turned into the position shown in Fig. 4 for opening the full supply the impingem'ent of the said stud j on the lever extension of the other cock turns the latter in the reverse direction, so that as the one cock is opened the other is closed, but the turning of the main-burner-cock lever in the opposite direction for cutting off the gas to extinguish the lamp does not affect the position of the initial supply cock lever, which remains closed, as shown in Fig. 5, until the burnerrequi'res to be again lighted. V

Any other connection between the levers of the two cocksmay be employed which will gas-fittings for lighting and heating purposes differs in no essential respect from its application to a street gas lamp as herein described.
